An email from Google is automatically sent to your recovery email address.

Log into the account of your secondary email address and follow the instructions provided in the message.

NOTE: If Gmail sends a verification email and you didn't receive the it, the message was probably caught by a spam or bulk mail filter in your recovery email system. Try checking your Spam or Bulk Mail folders for a message from account-recovery-noreply@google.com to see if the email ended up in there.

A text message will be sent to your mobile phone with a password-reset code.

Enter the password-reset code on the following Text message code verification page.

If you're unable to use any of your existing account recovery options on the password assistance page, click I no longer have access to these and you’ll be given a series of questions to verify that you own the account.

The questions we ask to verify your identity are intentionally difficult. Answer as many questions as possible, and make sure your answers are accurate. If you’re unsure about an answer, provide your best guess. It also helps to submit your answers from a computer you've used in the past.
